While it may seem confusing that a portion of the world that faced some of its worst wildfires on record last year is now facing a torrent of water, climate change is likely playing a role in both of these back-to-back disasters. An analysis released last year showed how climate change had increased the odds of extreme fire weather that fueled the bushfires. Though it’s harder to map climate change’s specific influence on individual heavy rain events like this one, experts agree that rainfall events are getting wetter and more frequent as the world warms.
